Bangkok to London flight guide
Flying from Bangkok to London
In short
Various airlines fly nonstop from Suvarnabhumi Airport (BKK) in Bangkok to London: British Airways, Thai Airways International, EVA Air and Norse Atlantic Airways. The flights use Heathrow (LHR) and London Gatwick (LGW). The 9,577 km journey takes about 12 hours 30 minutes, the longest nonstop sector out of Bangkok to Western Europe, and it carries holidaymakers, the UK's Thai community and business travellers.
Full-service airlines and Norse Atlantic's seasonal fares
British Airways, Thai Airways and EVA Air are full-service, with bags, meals and entertainment included. Norse Atlantic Airways is a long-haul low-cost airline: its basic fare covers the seat, and bags, meals and seat choice cost extra. Norse flies the route seasonally. Check whether your ticket lands at Heathrow or Gatwick, as the airports are on opposite sides of London.
Suvarnabhumi's SAT-1 for flights to Europe
All the airlines depart from Suvarnabhumi, 27 minutes from Phaya Thai on the Airport Rail Link. Wide-body flights to Europe often board at SAT-1, the satellite concourse with 28 gates; an automated train covers the tunnel of about one kilometre from the main terminal in about three minutes.
Heathrow Express or the Elizabeth line to Paddington
Heathrow is west of the city. The Heathrow Express runs from Heathrow Central (Terminals 2 and 3) to Paddington in about 15 minutes, with trains every 15 minutes and Terminal 5 a few minutes further. The Elizabeth line takes about 27 minutes to Paddington, stopping at six stations on the way, and continues through central London. The Piccadilly line is the slowest and cheapest. From Terminal 4, take the free shuttle train to Heathrow Central.
Gatwick Express and Thameslink
Gatwick lies south of London, linked to the centre by the Gatwick Express and Thameslink trains.
The UK ETA and its £20 fee
Visitors from 85 nationalities that do not need a visa, including those from the United States, Canada and France, must now hold an Electronic Travel Authorisation (ETA) before travel. GOV.UK lists the fee as £20 for an online or app application. British and Irish citizens, visa holders and people with permission to live, work or study in the UK do not need one. Other nationalities need a visa; use GOV.UK's checker for your passport.
Dhaka travellers changing at Suvarnabhumi for London
Travellers from Dhaka arrive at Suvarnabhumi on Biman, US-Bangla or Thai Airways (see our Dhaka to Bangkok flights page), the same airport as all the London flights. On separate tickets you clear Thai immigration and check in again, which needs permission to enter Thailand and a completed Thailand Digital Arrival Card. Dhaka also has its own flights to London: see Dhaka to London flights.

Norse Atlantic Airways flies the route seasonally. Airlines publish these changes in advance, but dates can move, so check the schedule before you book.
General
UK time is seven hours behind Thailand in winter and six hours behind during British Summer Time (late March to late October); Thailand does not change its clocks.
Yes. Fly Dhaka to Bangkok on Biman, US-Bangla or Thai Airways, all of which land at Suvarnabhumi, then take one of the London flights. Booking both legs on one Thai Airways ticket, where available, keeps you airside with your bag checked through. Two separate tickets mean clearing Thai immigration, which needs a Thai visa.
The Elizabeth line and the Heathrow Express run into central London, and the Piccadilly line is the cheapest option.
What's included
It depends on the airline. Norse Atlantic Airways is a low-cost carrier whose basic fares include only a cabin bag, so add checked baggage when you book. The full-service airlines normally include a checked bag; the allowance is shown on your booking.
Visa & documents
Visitors from 85 visa-free nationalities, including the US, Canada and France, need an Electronic Travel Authorisation before travel; GOV.UK lists the fee as £20. Other nationalities need a visa, so use the GOV.UK checker.
Stay & facilities
On the full-service airlines, request a Muslim (halal) meal when you book or at least 24 hours before departure through the airline's manage-booking page. On Norse Atlantic Airways, meals are bought online or on board; check the menu for halal options.
